LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 518,560, dated April 17, 1894.

Application filed November 18,1892. Serial No. 452,389- (No model.)

To (0% whom it may concern:

Be it known that I, STEPHEN S. BLACK, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Lawn-Sprinkler, of which the following is a specification.

My invention relates to that class of sprinklers intended to wet a square plot of ground, and consists of a nozzle adapted to screw on any suitable standard, the bore of the nozzle being divided longitudinally by two septa cutting each other at right angles, and protruding through the delivery orifice far enough to engage and support a trumpet shaped deflector supporting on its upper and plane surfaces a 'revoluble vane.

Referring to the accompanying drawings, Figure 1, is a side View of myinvention mounted on a low standard adapted to be drawn over the grass when in action by applying traction to the hose. Fig. 2 is a cross section throughthe line ma; of Fig. 1. Figs. 3 and 4, show the construction of the two septa. Fig. 5 is a vertical cross section through the head, showing the united septa'in side elevation, without the band. Fig. 6 is a top view of instrument mounted on standard. Fig. 7 is a cross section through the line 6, 6, in Fig. 1.

All lawn sprinklers with one exception are designed to wet a circular plot. In cities it is especially desirable to wet the ground in squares, as it is impossible with the ordinary circular spray to wet it evenly and at the same time avoid wetting the sidewalks. I accomplish this desirable result by dividing a nozzle of sufiicient capacity into four equal parts as shown in Fig.2, by means of two septa made from solid metal or preferably in the forms shown in Figs. 3 and 4, and adapted to be united by slipping the solid orunslotted end of one into the slotted end of the other, the two sheets or septa then crossing each other at right angles. They are now in order to be driven into the nozzle 5, Fig. 5, from the lower or threaded end until the small ends of the septa 6 project through the orifice and the beveled shoulders of same are solid other at right angles and of sufficient depth 1 to receive the septa which are together driven in snugly. The rim of the deflector is bent down slightly, at four points forming four lips, corresponding radially to the four angles formed by the intersection of the two septa as shown at 8, 8, Fig. 1. The amount of deflection should be suflicientto divert that portion of the stream from an upward direction to one nearly horizontal.

On the top of the deflector is a small vane 9, Fig. 1, pivoted by the screw in the center. This vane projects over the margin of the deflector sufficiently to form a little paddle at each end by turning it down diagonally as shown at 10, thus presenting an inclined surface to the stream as it issues from under the rim of the deflector B. The object of this revoluble vane is to catch and scatter asmall quantity of water in the space immediately around the instrument, which would otherwise not get quite enough. The vane is revolved by the sheet of water rushing outward and upward and acting on its turned=down ends. The nozzle 5, Fig. l is provided with four horns 12, 12, (be, Figs. 1 and 6 which serve as a grip for the hands and also as a protection for the upper parts in case of upsetting. The horns correspond to the corners of the square plot irrigated and serve as pointers in setting the instrument in position for action.

In Fig. 1, is shown a low standard 14 consisting of a street elbow provided with two legs 15, 15; the hose coupling 16 being attached directly to the standard itself. When coupled with a hose, the hose forms a third element of support giving abundant stability. The standard 14, Fig. 1, is provided with two lugs 17, 17, radiating outward with horizontal faces, adapted to form a horizontally movable joint with the legs 15, 15, when secured by rivets. Each lug is provided on its outer I tiens', as indicated ab0ve,;yvhieh portions, cove respond t0 the 'Sides; ef the square sprinkled I plot, theheayier portions offhestieam going greater eara [i y i e ers et hl' r er q watei hwhich they contain; :1 The four turned M down portiens ofthe rimiof 'thefieIieGtOr S, ,1
